BREsoH-LoAoine FIRE-ARM.

My invention is especially adapted to be used for a single-barreled breech-loading rifle, in which great solidity of action is necessaryto prevent derangement in the accuracy of its shooting.

It consistsjn certain improvements in the construction of thefore-end joint, by whicliT secure a neater appearance, a joint .which is stronger and less-liable to become loose with use, and which supports the barrel, when open,

upon a solid suriacwof considerable length.-

. The pin which forms the joint has an arm upon one end which projects up by the side of thebarrel, and a slide which carries the shell-extractor is connected with this arm, by which it is actuated.

The device by which the parts are locked'in position to be fired consists of a bolt sliding longitudinally into a notch beneath the barrel, and actuated by a doublearm or cam secured to a verticalshaft, which is turned in either di-. rection by the top lever to retract the bolt, but is at the same time independent from it. The bolt is latched by the action of a springupon a bell-crank lever, one 'end of which presses against the end of the bolt.

The frame is entirely independent of the lock, which may be of any form,and the firingpin which strikes the primer in the cartridge stands at an angle. so that a side-action lock operates nearly in a right line with the her of the gun. i

Referring to the accompanying drawings for a more complete explanation of my invention, Figure 1 is a side view of my gun with barrel Fig. 2 is a longitudinal section through the barrel and locking mechanism. Fig. his a View of the bolt and the double cam which operates it.

A is the barrel of my gun, and B is the frame into which the barrel fits and within which it swings, and P is the fore end. In the present case the barrel is octagonal in shape,

and the bed in the frame within which it rests rel, so that this proportion of the frame ex tends beneath the barrel in front of the pin.

In order to allow the barrel to drop or break down, as it is called, when unlocked, this front portion of the frame has its bed cut down at an angle with that portion of the bed behind the pin, as shown at D. When, therefore, the barrel is released and tiltsvdownward about the pin, that portion in front of the pin is supported and steadied by this octagonal inclined groove D, into which it exactly fits, (in the same manner that the rear portion of the barrel fits that portion of the'groove behind the pin when it is closed,) and the fore end is in nowise affected by the weight of the barrel.

This construction makes the motion of the barrel around the pin very exact, and prevents all side shake and greatly lessens the strain and friction on the pin and tore end'when the barrel breaks down.

' The front end of the frame is curved in the arcofa circle having the pin 0 as its center, and the fore end, P, is secured beneath the barrel forward of the frame, having its rear end formed with the same curve, so that it moves over the end of the frame when the barrel breaks down without leaving any opening between them. This preserves the symmetry of the stock when opened as well as.

when closed, and it prevents any possibility of the fingers becoming caught by the movement of the barrel.

In order to actuate the shell-extractor F, I employ an arm,'G, which extends upward from one end of the pin G to a point opposite the slide H, which carries the extractor. A pin projects from the slide into a slot in the arm G, and, as this pin is situated some distance bQltl and release the barrel closed is effected of a bell-crank lever,

bolt, slides through a slot in. the lower part of the frame, and has a plate, J, formed upon or secured across the rear end. The bolt is held forward in position to lock the barrel by means one arm, K, of which presses against the plate J ,while the other arni, L, is pressed downward bya flatorother spring, M, fixed beneath the tang of I the standing breech, as shown. In'order to withdraw the so that it may be opened, I employ a double-armed lever or cam,

N, which is secured. to the {25 sh'aft,,0,and just in front ition one end or the other of foot of a vertical of the plate J, so that when the shaft is turned in either directheeam will press against this plate and force it and the bolt baek against the resistance leverand'spring M but when released the spring acts to force the bolt forward again,

shaft 0 is turned in- 35 of the bell-crank and the cam will resume its normal position in front of the plate and'independent of it. he either direction by means ofati'prlever, P, which is'secured to its upper by'a sliding belt, I. This in a manner similar to this lar purpose. The lever and the vertical shaft for the purpose of actuating a locking mechanism for guns are notnew; but the whole combination of mechanism is dill'erentfrom others.

In my construction the lever may be turned equal facility; Only'one spring, M, is required in the whole gun outside of the leek, and when in its normal position the lever, shaft, and cam are entirely independent of the locking bolt and mechanism, so that the latter is latched by the simple into its place, the bolt moving back entirely independent of the lever and cam, whichare notmoved at all. 5
